4.2.1 Radio targets

Org can automatically turn any occurrences of certain target names
in normal text into a link. So without explicitly creating a link, the
text connects to the target radioing its position. Radio targets are
enclosed by triple angular brackets. For example, a target ‘<<<My
Target>>>’ causes each occurrence of ‘my target’ in normal text to
become activated as a link. The Org file is scanned automatically
for radio targets only when the file is first loaded into Emacs. To
update the target list during editing, press C-c C-c with the
cursor on or at a target.
